FT_DATATYPE_MVAR
Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_datatype_mvar”.
FT_DATATYPE_MVAR describes the FieldTrip MATLAB structure for multi-variate autoregressive model data. The mvar datatype represents multivariate model estimates in the time- or in the frequency-domain. This is usually obtained from FT_MVARANALYSIS, optionally in combination with FT_FREQANALYSIS. The following is an example of sensor level MVAR model data in the time domain dimord: 'chan_chan_lag' defines how the numeric data should be interpreted label: {3x1 cell} the channel labels coeffs: [3x3x5 double] numeric data (MVAR model coefficients 3 channels x 3 channels x 5 time lags) noisecov: [3x3 double] more numeric data (covariance matrix of the noise residuals 3 channels x 3 channels) dof: 500 fsampleorig: 200 cfg: [1x1 struct] The following is an example of sensor-level MVAR model data in the frequency domain dimord: 'chan_chan_freq' defines how the numeric data should be interpreted label: {3x1 cell} the channel labels freq: [1x101 double] the frequencies, expressed in Hz transfer: [3x3x101 double] itransfer: [3x3x101 double] noisecov: [3x3 double] crsspctrm: [3x3x101 double] dof: 500 cfg: [1x1 struct] Required fields: - label, dimord, freq Optional fields: - too many to mention Deprecated fields: - <none> Obsoleted fields: - <none> Revision history: (2011/latest) The description of the sensors has changed, see FT_DATATYPE_SENS for further information. (2008) The initial version was defined.
